I really like Microsoft Office documents… They offer so many features that can be (ab)used to make them virtual bombs. Yesterday, I found a simple one but nicely prepared Powerpoint presentation: Payment_copy.ppsx (SHA256:7d6f3eb45c03a8c2fca4685e9f2d4e05c5fc564c3c81926a5305b6fa6808ac3f). It was still unknown on VT yesterday but it reached now a score of 1/61![1]. It was delivered to one of my catch-all mailboxes and contained just one slide.
